Comprising of the Paleozoic, Mesozoic and Cenozoic eras, this eon spans 541 million years from the Cambrian Explosion to today.
During the Paleozoic era, complex life started to appear. It took 100 million years for the aquatic plants and animals to migrate to land. Then, another 130 million years later, giant bugs started to appear. 60 million years later, entire coalfields from the Carboniferous Rainforest Collapse Event were set on fire by volcanic activity, causing the Permian-Triassic extinction. The Mesozoic era had begun.
20 million years later, dinosaurs started to appear. They died altogether during the Cretaceous-Paleogene extinction 66 million years ago beginning the Cenozoic era. The mammals started to dominate land. 60 million years later, the Mediterranean Sea drained up, but quickly refilled due to closure and reopening of the Strait of Gibraltar. 6 million years later, humans finally appeared, ending the story of earth's life as we knew it.

An MTR line that originates from its terminus at North Point and ends at its two other termini at Po Lam and LOHAS Park, bifurcating at Tseung Kwan O.
History:
2002 - Tseung Kwan O Line from North Point to Po Lam is built, taking over part of the Kwun Tong Line, including its cross-harbour section, with North Point and Quarry Bay as interchange stations with the Island Line, and Yau Tong and Tiu Keng Leng as interchange stations with the Kwun Tong Line.
2009 - Tseung Kwan O Line from Tseung Kwan O to LOHAS Park is built, with Tseung Kwan O as the line's bifurcation station.

A very short lived supercontinent. It formed in the beginning of the Ediacaran period of the Proterozoic Eon, but broke apart as Laurentia rifted away from the rest of the supercontinent. It broke apart even before the Phanerozoic Eon and the Cambrian period. Not so well-known although is one of the only interesting things that happened during the Ediacaran period.
Bob reading out loud from a website: 630 million years ago, Pannotia formed.
Kate: Pannotia? Do you mean Pangea?
Bob: The Ediacaran supercontinent, not the Permian one.
Kate: I thought the only supercontinent was Pangea!
Bob: How about this?
Bob reading out loud from a website again: Pannotia was the result of supercontinent Rodinia turning inside out 720 million years ago.

Silane is a pyrophoric gas. Its chemical formula is SiH4.
It spontaneously ignites when in contact with air. (SiH4+2O2->SiO2+2H2O)
Commonly produced with the following process:
1. Silicon dioxide is burned with magnesium, forming magnesium silicide. (SiO2+2Mg->Mg2Si+O2)
2. The magnesium silicide is placed into hydrochloric acid, forming silane gas, which ignites as it bubbles out of solution. (Mg2Si+4HCl->2MgCl2+SiH4)

Evelyn: I just made silane gas from household chemicals!
Tom: Nice! Did it explode or ignite?
Evelyn: It popped as it bubbled out. What an interesting gas.
